BHK Sig. 250 ?

This amp is on my short list...May take the plunge in a week or so. I would be replacing a Parasound A-21.

Update:  I bought a BHK 250 over two weeks ago.  When it arrived, I hooked it up but it appeared to be defective with a persistent ground loop/white noise issue even with nothing hooked up to it other than speaker cables.  I contacted PS Audio and discussed the issue with them.  They walked me through some diagnostic checks and they determined that the amp had a problem.  PS Audio built and tested a replacement which is on the way to me.  They are sending the replacement using their "white glove" service at no additional cost to me.  As part of this level of service, they will remove the defective amp and send it back to PS Audio.  Although I ordered the amp from an authorized dealer, PS Audio stepped up and took responsibility.  They promised to make things right. I couldn't be more impressed with their customer service. Now, finger's crossed that the replacement will work as intended.  I just bought a Moon Evolution 740p pre-amp that is very lonely and missing an amp to play with. :-)

BHK 250 arrived a couple of days ago.  I am very satisfied with its performance.  No issues like the first one I had.  No regrets moving up from a Parasound A-21.  PS Audio has hit one out of the ballpark.
